UNITED STATES PATENT (DEETcEo GYRUS GREEN, OF HESPELER, ONTARIO, GAN ADA.

IMPRovMEN-r IN FORCE-PUMPS.

Specification forming part of Letters PatentvNo. 187,755, dated February 27, i877, application led July 29, 1876.

To all 'whom it may concern:

Be it known that I, GYRUS GREEN, of the village of Hespeler, in thecounty of Waterloo, in the Province of Ontario. Canada, have invented certain new and useful Improvements in Force-Pumps 5 and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to those pumps which are placed in the bottom of the well, the dischargepipe from which rises above the mouthY thereof', and which I utilize for supporting the working-gear of the same. It consists of two upright cylinders anged at the bottom, and

secured to a bed-piece in the bottom of the well. The cylinders are constructed with slots, and are each of them provided with a working-bucket and a stationary valve, and are connected to each other at the top by elbows and other suitable pieces, and forming, when so connected, a double pump; but, with one discharge-pipe common to both, which rises from the middle of the connection-pipes, and projects above the mouth of the well, the. advantages gained from the two cylinders being that a given quantity of water is lifted or forced a given height in a given time with less motive power than with one cylinder only, and also that the pump can be used with either one or two cylinders, as may occasionally be required. In addition to the two cylinders and 011e discharge-pipe there are two crossheads operated by two side rods attached to the same, and to au oscillating beam above, which is pivoted on a center piece embracing the discharge-pipe. The oscillating beam aforesaid is operated by means of a cranked shaft located on a bracket secured to the aforesaid `dischargelpipe above the mouth of the well,

and two connecting-rods attached to the shaft and the beam complete the arrangements.

Another object of my invention is to obtain a pump which shall be simple in its construction and operation, which shall be worked,as hereinbefore described, bythe least possible Y motive-power, and not be liable to derangement from frost or other causes. v

Figure l is an elevation of my pump showy ing the cylinders A A with slots a, a, crossheads B B, side rods C O, oscillating beam D, center piece d, connecting-rods E E, bracket F, crankshaft Gr, winch H, discharge-pipe P, with branch P. Fig. 2 is an end elevation showing one of the cylinders A in section, with working bucket a and stationary Vvalve a', cross-head B, side rods C C, oscillating beam D, center piece d, connecting-rod E, top bracket F, crankshaft G, Iwinch H, discharge pipe P, with branch P.

The connecting-rods E E'and dischargepipe P are made to suit the varying depths of wellsin which my pump is to be used.

It will be seen on leference to the drawings that, by turning, the winch H will rotate the shaft Gr, which, bymeans of the connecting-rods E E, will oscillate the beam D, which, by means of the side rods C C, will give a reciprocating' motion, vertically, to the cross-heads B B and the working buckets a a attached to the same, which will cause a vacuum in the cylinders A A, into which vacuum the water will dow, and, on the downstroke of the buckets c, will be forced through the same, and, by the up-stroke of the buckets c", the water will be forced through the stationary valves a', and will fill the dischargepipe P and be delivered therefrom at the branch P', or by using a hose andrnozzle it may be distributed as otherwise required.

Having thus described my invention, Iv

rIhe combination ofthe cylinders A A, connection-pipes A A', discharge-pipes P, crossheads B B, side rods C O, oscillating beam D..
